None of the above proposed systems have proved to I be commercial due to the complexity of the adjusting I mechanism. These complex structures are not only costly, but in addition, interfere with compactstor'age and hanging. A further limitation in each of these structures is their inability to readily convert to astand type structure. These structures are further limited in that they will only hold articles of a selected thickness. A further limitation in some of these structure is that the frame portions are not positively locked in place.

BRIEF DESCRIPTION The present invention comprises an adjustable frame comprising four corner members interconnected by cross braces.

The cross braces comprise thin plastic strips which can be cut down or bent back so as to adjust the cross braces to any desired frame size. The cross braces are formed with a plurality of apertures so that after. the strip is cut down or bent back, an aperture is available for attaching the strip to a headed member provided on each of the corner members. The headed members are selectively positioned on the corner members so as to assure that the brace can be made tight. The apertures in the braces are also utilizedto anchor a suspension wire so as to allow the framed articles to be hung, if desired. I i

The braces lie flush with the corner members so as not to protrude from the back of the frame and thereby interfere in hanging or with compact storage of framed articles.

The frame easily converts to a stand type structure by the incorporation of stand receiving means in each of the corner members. The stand receiving means allows for selective positioning of the frame on its end or on its side. The stand is L-shaped and selectively inserted corner members. In a still'further embodiment of the invention, the corner members are made of pliable plastic so as to resiliently grasp the article to be framed. In both of these modifications, the spring means is sufficiently resilient to adjust to articles of various thicknesses.

2 f In a still further embodiment of the invention, cross braces extend across both faces of the frame to provide rigid support while in another embodiment the cross braces are eliminated to permit viewing pictures on opposite surfaces of the frame.

DETAILED DESCRIPTION Referring to. FIG. 1, a picture 1 is shown having a frame 3 constructed in accordance with the present invention.

While the present invention will be described and illustrated in connection with a picture or thelike, it is to be understood that the frame can be used in connection with variousarticles which have need for a frame. As an example, the present invention has application in packaging and in transporting sheets of material such as thin metal. It is particularly applicable where the surfaces of the sheet metal have to be protected from marring and in cases where it is desired to prevent thin h sheets from creasing. In these applications, protective boards of adirnension equal to the dimension of the sheet metal are placed in contact with opposite sur-' faces of the metal, and the frame of the present invention is then utilized to hold the assembled sheets together and to offset the assembled sheets from contact with adjacent surfaces.

As shown in FIG. I, the frame 3 comprises corner members 3A, 3B,'3C and 3D. The corner members may be constructed from any suitable material such as wood, rigid foam, metal and preferably, are formed of plastic. I

Referring to FIG. 2, each corner member is grooved, as shown at 5, to fit about the corners of picture 1. Picture l is snugly engaged by the comer members 3A, 3B, 3C and 3D as it is wedged between a glass or trans parent plastic sheet 7 and one or more backing pieces sectional view takenalong line IVIV of 3 9. The backing piece may comprise cardboard, masonite, or the like.

Referring to FIG. 3, a rear view of the frame 3 is shown. The corner members 3A, 3B, 3C and 3D are interconnected and locked to picture 1 by cross braces 11 and 13 which extend diagonally across the back of the picture. The cross braces are made of thin plastic material, such as cellulose butyrates, one 30-second of an inch thick, which is capable of being bent upon itself or cut by scissors, razorblade, knife or the like, so as to permit the cross braces to be cut cown or bent back to a size corresponding to the diagonal dimension of the picture. It is to be understood that the cross braces may be made from any suitable plastic and thickness as long as it is capable of readily bending and/or being cut. The cross braces are initially made extra long to accommodate extra large pictures.

The cross braces 11 and 13 include apertures 15 and 17 at one end for anchoring the braces to corner members 3C and 3D respectively. The braces are connected by snap fitting apertures 15 and 17 (see FIG. 4) over headed pins 19 and 21 integrally formed on the corner members 3C and 3D; respectively.

Each of the cross braces 11 and 13 are also provided witha'series of apertures 23 and 25, respectively, so that an aperture is available for attaching the brace to headed pins 27 and 29 releasably secured to corner members 3A and 38, respectively. After securing the braces by way of apertures 23 and 25, the cross braces are cut down. This method allows extra lengths of the cross braces to serve as a convenient grip while attach- Referring to FIG. 5, pin holes 31A, 31B and 31C are provided in corner member 3A for releasably and frictionally receiving pin 27. These holes are spaced apart a predetermined distance, e.g., one-fourth of an inch while apertures 23 are also spaced a predetermined smaller distance, e.g., threesixteenths of an inch. This arrangement assures that one of the holes 31A. 31B and 31C will lie between one-eighth and one-sixteenth of an inch outwardly from one of the apertures 23. When the pin 27 to be inserted in such outer aperture, the plastic cross brace 11 is then stretched so as to snap over the pin 27. In this manner, the cross brace is made tight. The same arrangement is provided in connecting cross brace 13 to headed pin 29 in corner member 38.

It is to be understood that apertures 23 and pin holes may be spaced greater or smaller distances depending on the degree to which it is desired to make the cross braces taut.

As hereinbefore described, the cross braces are made extra long so as to accommodate large pictures. Generally, the braces have to be cut down, e.g., by cutting with a scissor the extra length portions shown in broken lines in FIG. 3. In the alternative, the-cross braces may be bent back upon themselves as shown in FIG. 5 and as hereinafter more particularly described.

It will be noted that even after the cross braces are cut down, the frame can be made to accommodate pictures of smaller dimension merely by cutting down further on the cross braces. The series of apertures 23 and 25 extend along the cross braces to a sufficient extent so as to allow an adjustment down to a size where the corner members 3A, 3B, 3C and 3D are abutting. If a purchaser desired to frame a larger article, it is only required that he purchase four cross braces of suitable length. In its commerical form, the initial package may include such extra braces.

The cross brace need not be cut down. As shown in FIG. 5, the cross brace 11 is bent back upon itself at 11A with the apertures aligned so as to permit the strip to be snapped over pin 27. This arrangement allows the cross brace to be subsequently used in framing larger as well as smaller pictures.

Referring to FIG. 3, the series of apertures 23 and 25 perform a second function as selected horizontally aligned apertures 23A and 25A in each series are used to anchor suspension wire 33. The wire 33 is simply extended at each of its ends, through apertures 23A and 25A and wrapped about itself as indicated at 35 and 37. The wire 31 is of sufficient length so as to provide slack for hanging the framed pictures.

Referring to FIGS. 3, 4 and 5, each of the corner members 3A, 3B, 3C and 3D include channels 39 for receiving the cross braces 11 and 13 so that the cross braces are, flush with the outer surface of the corner members. In this manner, there is a minimal interference in hanging the framed picture. When the frameis used to assemble sheet material, the flush arrangement allows a plurality of framed sheets to be compactly arranged during storage and transportation. The channels 39 include diverging walls 40 so as to accommodate the cross braces in various angular positions within'the size adjustment range.

Referring to FIG. 6, a modification of the present invention is shown which is particularly adapted to be used in framing paintings and assembled sheets as hereinbefore described. In this embodiment, the corner members 3W are modified to include clamps 41 securing the corner members to the framed article. The clamps 41 are spring biased and can accommodate framed articles of varying thicknesses.

As shown in FIG. 6, the framed article is a painting comprising a canvass 43 mounted on a rectangular frame 45. Each of the clamps 41 comprise single bend twenty-five one thousanth shim steel plates, cemented or otherwise secured, at one end to a recess 47 in each of the corner members 3W. The other end of the spring clamps bear against the frame 45 as indicated at 49 in FIG. 7.

The spring clamps 41 are mounted so as not to project from the corner members and interfere with hanging or storage. Rather than cementing the clamps 41 to the corner members, the same may be removably connected by, e.g., a conventional cooperating detent and recess arrangement (not shown) on the clamp 41 and in recess 47, respectively. This has the advantage of allowing ready replacement in case of breakage or wear.

The edges of the framed article in FIG. 6 are finished by plastic frame portions 51 which extend between the corner member giving the appearance that the frame is continuous. The frame portions 51 extend into recesses 53 formed-in the corner members with the fit sufficiently snug to hold frame portions 51 in place. Frame portions 51 are also made of thin plastic material and are initially provided in extra long lengths capable of being cut down to the required dimension.

Rather than frame portions 51, plastic coated cloth tape (not shown) may be extended between the corner members 3W in order to finish off the frame edges intermediate the corner members.

Referring to FIG. 8, a modified corner member 3X is shown wherein one side wall 55 of the corner mem- V ber converges toward the other side wall 57. Comer member 3X is made of a plastic material so that wall 55 capable of self support. It is preferred that each of the corner members include stand receiving means so that the frame can be supported on end or on its side.

When using corner members as illustrated in FIG. 8, frame portions 63, similar in function to frame portion 51 shown in FIG. 6 and above described, may be pro vided to extend between the corner members so as to give the impression that the frame is continuous. As shown in FIG.,9, frame portions 63 are made of pliable plastic and comprise a base wall 65, sidewall 67 and an opposed sidewall 69 converging toward sidewall 67 so as to resiliently and adjustably grasp the article to be framed. The frame portions 63 are received in recess 70 formed in corner member 3X so as to give the frame a continuous appearance.

The stand receiving means comprise angled bores 71 which are adapted to receive L-shaped rod stands 73 as illustrated in FIG. 7. It will be noted that the stand rods '73. extend substantially adjacent to the surfaces on which the frame is supported due to the angle of bore 71. This permits a weight to be rested on the stand and effectively hold the same when the occasion demands. One leg 75 of the L-shaped rod stand 73 prevents the weight from falling off the stand.

The L-shaped rod stand 73 permits alternate stand arrangements. As shown in FIG. 10, the short leg 75 is rotated 180 so as to permit the short leg to be embedded in the ground. As shown in FIG. 11, the short leg 75 is inserted in bore 71 and the long leg is embedded in the ground so as to support the frame in the elevated position.

As hereinbefore described, the cross braces have been described as flexible members so as to allow the same to be easily cut down or bent back. In storage and transportation applications, ease in cutting may not be a requirement and the cross braces could be made rigid extending across both the front and rear faces of the framed article as shown at 77 and 79 in FIG. 12 to provide double structural support. In this instance, the extra lengths of cross brace would have to be sawed off or otherwise removed by equivalent means.

The corner member 3Y used in FIG. 12 is shown more particularly in FIGS. 13 and 14. Corner member 3Y includes opposed channels 81 and 83 for receiving cross braces 77 and 79 within the confines of the corner membersso as to allow compact stacking of framed articles.

Except for their rigidity, the cross braces77 and 79 are identical to the cross braces hereinbefore described including a plurality of apertures 85 to permit adjustcross brace to the corner member. Walls 91 and 93 of her. This permits the cross braces 77 and 79 to pivot to a greater extent so as to permit greater freedom in adjustment to accommodate sheets of various size.

The corner member 3Y as shown in FIG. 13 is adapted to receive sheets of material 99 and 101, one of which is the sheet being transported and the other of which is a protective intermediate and cover sheet.

These sheets 99 and 101 are supported by a sheet support flange 103 on corner member 3Y and are held thereagainst by cross brace 77.

Referring to FIGS. 15 and 16, a further modification of the present invention is shown wherein the cross braces are eliminated. In this embodiment, stands 105 and 107 are provided so as to stand the frame in a vertical position and permit viewing of pictures mounted in both sides of the frame.

Referring to FIG. 16, an exploded view of a corner member 3Z used in FIG. 15 is shown together with frame members 109. The corner member 32 in FIG. 15 is similar to the corner member of FIG. 8 in that it is made of pliable plastic and it is adopted to be spring biased about the framed article. In this embodiment, the

corner member 32 includes two converging sidewalls 111 and 113. Frame member 109 is received in a recess 115. At the extremity wall 111 an aperture 115 is provided through which a nail 7 is hammered so as to hold the frame members 109 in place. v
